Presence Of Retinal Tear Research Articles

Use of Optical Coherence Tomography in Detecting Retinal Tears in Acute, Symptomatic Posterior Vitreous Detachment.

To evaluate the association of posterior vitreous opacities (PVO) on optical coherence tomography (OCT) with retinal tears identified on exam, in patients with acute, symptomatic posterior vitreous detachment (PVD). Data was retrospectively collected from the medical records of 388 patients with acute, symptomatic PVD between January 1, 2021, and June 30, 2021. Included patients had received a primary diagnosis of PVD and presented with flashes and/or floaters. OCT scans were reviewed by two separate readers for the presence of PVOs. The primary outcome was the presence of retinal tear on fundus photo and on exam. Of 388 patients who presented with acute PVD symptoms, 90 (23.2%) were found to have a retinal tear on dilated fundus exam. Among these patients, 78 (86.7%) were found to have PVOs on OCT. Statistical analysis demonstrated a significant relationship between the presence of PVOs and retinal tear (p < 0.01). The sensitivity and specificity of this finding was 86.7% and 72.5%, respectively. Further analysis included Area Under the Curve (AUC) from Receiver Operating Characteristic (ROC) Curve which was found to be 0.80. The presence of PVOs on OCT is suggestive of a retinal tear in patients with acute, symptomatic PVD.

Complications of Acute Posterior Vitreous Detachment

To evaluate the risk factors for retinal tear (RT) or rhegmatogenous retinal detachment (RRD) associated with acute, symptomatic posterior vitreous detachment (PVD) in a large comprehensive eye care setting. Retrospective cohort study. A total of 8305 adult patients in the Kaiser Permanente Northern California Healthcare System (KPNC) during calendar year 2018 who met inclusion criteria. The KPNC electronic medical record was queried to capture acute, symptomatic PVD events. Each chart was reviewed to confirm diagnoses and capture specific data elements from the patient history and ophthalmic examination. Presence of RT or RRD at initial presentation or within 1 year thereafter. Of 8305 patients who presented with acute PVD symptoms, 448 (5.4%) were diagnosed with RT and 335 (4.0%) were diagnosed with RRD. When considering variables available before examination, blurred vision (odds ratio [OR], 2.7; confidence interval [CI], 2.2-3.3), male sex (OR, 2.1; CI, 1.8-2.5), age < 60 years (OR,1.8; CI, 1.5-2.1), prior keratorefractive surgery (OR, 1.6; CI, 1.3-2.0), and prior cataract surgery (OR, 1.4; CI, 1.2-1.8) were associated with higher risk of RT or RRD, whereas symptoms of flashes were mildly protective (OR,0.8; CI, 0.7-0.9). Examination variables associated with a high risk of RT or RRD included vitreous pigment (OR, 57.0; CI, 39.7-81.7), vitreous hemorrhage (OR, 5.9; CI, 4.6-7.5), lattice degeneration (OR, 6.0; CI, 4.7-7.7), and visual acuity worse than 20/40 (OR, 3.0; CI, 2.5-3.7). Late RTs or RRDs occurred in 12.4% of patients who had vitreous hemorrhage, lattice degeneration, or a history of RT or RRD in the fellow eye at initial presentation but only 0.7% of patients without any of these 3 risk factors. Refractive error had an approximately linear relationship with age at presentation of PVD, with myopic patients presenting at a younger age (r= 0.4). This study, based in a comprehensive eye care setting, found the rate of RT and RRD associated with acute PVD to be lower than rates previously reported by retina subspecialty practices. Several patient features strongly predicted the presence of initial and late complications of acute PVD.

Vitreous Hyper-Reflective Dots in Optical Coherence Tomography and Retinal Tear in Patients with Acute Posterior Vitreous Detachment

ABSTRACTPurpose: To report the presence of hyper-reflective dots in the vitreous cavity using spectral-domain optical coherence tomography (SD-OCT) in patients with acute symptomatic posterior vitreous detachment (PVD) and investigate their association with the presence of retinal tear.Methods: The medical records of 77 patients with acute symptomatic PVD, who were examined between March 2013 and February 2015, were reviewed. The severity of vitreous hyper-reflective dots (VHDs) was graded using SD-OCT images, and the presence of retinal tear was assessed.Results: Forty-one (53.2%) eyes had mild VHDs, 13 (16.9%) eyes had moderate VHDs, and 14 (18.2%) eyes had severe VHDs. Retinal tear was found in 21 (27.3%) eyes. The presence of severe VHDs was associated with an increased likelihood of retinal tear (positive likelihood ratio, 9.78; 95% confidence interval, 3.02–31.63). In 14 (66.7%) eyes with retinal tear, the mean number of VHDs significantly decreased from 23.2 ± 20.27 to 2.3 ± 2.66 at a mean follow-up interval of 2.8 ± 1.48 weeks (P = 0.002).Conclusions: The presence of severe VHDs is suggestive of retinal tear in patients with acute symptomatic PVD. However, this SD-OCT finding should be limited to the acute phase of PVD.

The incidence of retinal breaks in the presenting and fellow eyes in patients with acute symptomatic posterior vitreous detachment and their associated risk factors.

To determine the incidence of retinal breaks in presenting and fellow eyes in patients with acute symptomatic posterior vitreous detachment (PVD) and their associated risk factors. A prospective study of 101 consecutive patients presenting with acute symptomatic PVD. The PVD status and other relevant ophthalmic findings were noted for both presenting and fellow eyes at initial presentation. Patients with PVD in the fellow eye were followed up appropriately whereas those without were invited to return for a further examination 4 years later. Data analysis was performed using general linear model and logistic regression. The mean age was 62 years. Seventy-six eyes had PVD in the presenting eyes, which were more myopic than their fellow eyes. Increased myopia and the presence of vitreous and/or retinal hemorrhage were associated with the presence of retinal tear(s) (P = 0.03 and P < 0.0001, respectively) at presentation. Twenty-three of the presenting eyes and 2 of the fellow eyes had have retinal break(s) at the first clinic visit. Of those, 14 eyes were found not to have a visible Weiss ring. Only 5.9% of the eyes (3 presenting eyes and 3 fellow eyes) developed delayed retinal break(s). Acute symptomatic PVD is a common presentation. It is essential to perform thorough examination to both presenting eye and fellow eye at initial presentation and follow-up appointments to prevent delay of treatment to retinal break(s).

VITREOUS FLOATERS AND PHOTOPSIA AS PREDICTORS OF VITREORETINAL PATHOLOGY

Salah Zuhair Al-Asadi MB,ChB, FRCS, FIBMS, Lecturer of Ophthalmology, College of Medicine, University of Basrah. Abstract Floaters and photopsia are common eye symptoms. This prospective study aims to detect the relative importance of floaters, photopsia, or both as predictors of vitreo-retinal pathology. In this study, 202 patients attending the outpatient clinic in Basra General hospital between 2009–2011 complaining of floaters, photopsia, or both were interrogated, starting with inquiry about the mode of presentation, then slit lamp examination of the anterior segment, and dilatation of the pupil by mydriacyl drops 0.5% and phenylphrine drops 10%, followed by 3 mirror examination of the vitreous and peripheral retina. The results showed that 98 patients were males while 104 patients were females, 104 patients (51.49%) presented with floaters; 24 patients (11.88%) presented with photopsia; and 74 patients (36.63%) presented with both floaters and photopsia, 102 patients (50.50%) had posterior vitreous detachment (PVD) while 52 patients (25.74%) had synchysis, and 48 patients (23.76%) had normal vitreous. The highest percentage of PVD was in the age group 60–69 years and was 40 patients (39.21%). Regarding the mode of presentation, the highest percentage of PVD was in the group of patients presenting with both floaters and photopsia and was 46 patients (62.16%). The total number of retinal tear cases detected was 14, 8 of them were present in patients having PVD and presenting with floaters and photopsia, while 4 cases of retinal tears were detected in patients having PVD and presenting with floaters, and finally 2 retinal tear cases were detected in patients having PVD and presenting with photopsia, 12 eyes (85.71%) who had retinal tears had vitreous pigment granules, while 2 eyes with retinal tears (14.29%) did not have vitreous pigment granules. In conclusion, the symptoms of floaters, photopsia, or both are an important predictors of vitreo- retinal pathology. A significant number of patients had PVD, and this was associated with retinal tears in a number of patients. Vitreous pigment granules in these patients were closely correlated with the presence of retinal tears. Careful examination of patients including 3 mirror contact lens examination is mandatory.

ORAL ANTICOAGULATION AND THE RISK OF VITREOUS HEMORRHAGE AND RETINAL TEARS IN EYES WITH ACUTE POSTERIOR VITREOUS DETACHMENT

To determine if oral anticoagulation alters the association between vitreous hemorrhage (VH) and retinal tears in eyes with acute, posterior vitreous detachment (PVD). In this retrospective chart review, the complete records of consecutive patients with spontaneous, symptomatic acute PVD from a single referral-based practice were reviewed. The use of oral anticoagulants, the presence of a VH, and the presence of a retinal tear or detachment were recorded. A total of 336 consecutive eligible patients (336 eyes) were included in the final analysis. Vitreous hemorrhage occurred in 118 (35%) eyes; in 43% of patients taking aspirin, clopidogrel, or warfarin versus 31% not taking these medications (P = 0.03). Retinal tears occurred in 46% of patients with VH versus 27% of patients without VH (P = 0.0007). Retinal tears occurred in 39% of patients with VH taking aspirin, clopidogrel, or warfarin compared with 52% of patients not taking these medications. (P = 0.20) A decreased proportion of patients with acute PVD taking one or more of the oral anticoagulant medications studied, regardless of the presence of VH, were diagnosed with a retinal tear (P = 0.0017) or retinal detachment (P = 0.0001). Retinal tears are commonly found (46%) in the eyes of patients who present with symptoms and signs of acute PVD and VH. Patients taking aspirin, clopidogrel, or warfarin who develop an acute PVD are more likely to present with VH. No statistically significant association was demonstrated between the use of oral anticoagulants in patients with acute PVD and VH and the presence of retinal tears or retinal detachment.

RETINAL TEARS AND RETINAL DETACHMENT AS FACTORS AFFECTING VISUAL OUTCOME AFTER CATARACT EXTRACTION COMPLICATED BY POSTERIORLY DISLOCATED LENS MATERIAL

To evaluate the incidence and effect on visual acuity of complicating factors such as retinal tears (RTs) and rhegmatogenous retinal detachment (RRD) in eyes with posteriorly dislocated lens fragments after cataract extraction. Retrospective consecutive series of patients presenting at a referral vitreoretinal practice with posteriorly dislocated lens material after cataract extraction over a period of 8 years. The presence of RT, RRD, endophthalmitis, and choroidal hemorrhage was noted, and their effect on visual outcome was studied. A total of 307 eyes with posteriorly dislocated lens material after cataract extraction were identified. Fifty-eight eyes (19%) were managed medically (Group I), whereas the other 249 eyes (81%) underwent pars plana vitrectomy for removal of the lens material (Group II). Indications for surgical management included uncontrolled inflammation, elevated intraocular pressure, and large lens fragments. No eyes in Group I developed RT or RRD. Of the 249 Group II eyes, 13 (5%) were found to have RT, and 25 (10%) developed RRD. In Group II, choroidal hemorrhage and endophthalmitis were noted in 12 (5%) and 4 (2%) eyes, respectively. Fifty-one (88%) of 58 eyes in Group I and 138 (55%) of 249 eyes in Group II achieved a final visual acuity of 20/40 or better. Seven (54%) of the 13 eyes with RT and 9 (36%) of the 25 eyes with RRD achieved a final visual acuity of 20/40 or better. In the RRD group, 9 (56%) of the 16 macula-on eyes achieved a final visual acuity of 20/40 or better, whereas none of the 9 macula-off eyes had a final visual acuity of 20/40 or better. None of the 4 eyes with endophthalmitis and only 1 (8%) of the 12 eyes with choroidal hemorrhage had a final visual acuity of 20/40 or better. Five (62%) of eight eyes with retinal detachment treated with pneumatic retinopexy needed further treatment with scleral buckle to achieve anatomical reattachment. A good visual outcome (20/40 or better) is possible in eyes with posteriorly dislocated lens fragments after cataract extraction, even when retinal tears or macula-on retinal detachment is present. The presence of a macula-off retinal detachment, however, has a significant adverse effect on the visual outcome. Pneumatic retinopexy is not associated with retinal reattachment in many cases and is not preferred.

The Ocular Complications of Boxing

In cooperation with the New York State Athletic Commission, 74 boxers applying for a new or yearly renewal license were sequentially referred over a 2-year period for a complete dilated ocular examination at the Sports Vision Institute of the Manhattan Eye, Ear and Throat Hospital. At least one ocular injury was found in 66% of boxers. Vision-threatening injuries, defined as significant damage to the angle, lens, macula, or peripheral retina occurred in 58% of boxers. Nineteen percent of boxers had angle abnormalities. Nineteen percent of boxers had pathologic cataracts, over 70% of these were posterior subcapsular. Six boxers had macular lesions. A total of 24% of boxers had retinal tears. Standardized photographs were used to distinguish pathologic cataracts from congenital opacities and pathologic retinal tears from atrophic holes. Attempts were made to identify risk factors in boxing that might be predictive for ocular injury. Variables included age, weight division, left- or right-handedness, total number of losses, and total number of bouts. Significant correlations were found between the total number of bouts and the total number of losses, and the presence of retinal tears. College varsity athletes were selected as controls. Significant differences were found between boxers and controls for the total number of injuries, total vision-threatening injuries, and the number of retinal tears. A series of recommendations are proposed to aide in the early detection and prevention of serious ocular injuries.
