RESUMO

Purpose: To study appropriateness of our modified screening criteria for detection of all cases of Retinopathy of Prematurity [ROP] among preterm babies


Method: Retrospective observational cohort study among preterm neonates who underwent ROP screening as per set protocol for 11 years at Nizwa Hospital, Al Dhakilya Governorate, Oman. We screened all babies with gestational age 32 weeks of GA or BW > 1500 g with unstable clinical course believed to be at high risk by the attending neonatologist also were screened


Results: During the study period 528 babies were screened for ROP of which 76 babies were excluded due to death, associated congenital ocular malformation and loss for follow-up either due to transfer to other institution or defaulting. Thus 452 babies were included in the final analysis. Incidence of ROP was 46.4% of which 27.9% had mild ROP, 11.3% had severe ROP which regressed and 7.3% had severe ROP who were treated. The incidence of ROP among infants with GA < 26 wks, 26-28 wks, 29-30 wks, 31-32 wks and above 32 weeks was 100.0%, 80.0%, 59.3%, 34.4% and 19.4% respectively. 56 babies of this cohort belonged to Extended [modified] criteria group. Among these 12 babies had ROP out of which 9 had mild ROP and 3 had severe ROP. Among cases with severe ROP, two cases regressed spontaneously and one case needed treatment. Multivariate analysis using stepwise regression model showed statistically significant association of GA and BW to development of ROP. We would have missed few babies with ROP if we had followed other criteria


Conclusion: Our modified screening criteria seem to be appropriate as no infant with severe ROP was missed during the study period. Incidence of severe ROP among babies in the extended criteria group [5.4%] is low but significant compared to lower gestational age. We plan to formulate a scoring system following all risk factor analysis to enable us to optimize the number of infants screened. Detection of all babies with ROP is important as they need long-term follow-up for the timely detection and management of associated ocular comorbidities

RESUMO

This report describes a middle-aged man presenting to the ophthalmologist with history of seeing floaters before both eyes since 2-weeks duration. A history of intermittent headache and dizziness of recent onset was elicited on questioning. Ocular examination showed bilateral early papilloedema and mild vitreous hemorrhage. Brain computed tomography [CT] disclosed features suggestive of colloid cyst of the third ventricle in the region of foramen of Monro with moderate hydrocephalus. Emergency craniotomy and excision of the cyst was done, and the patient is doing well for the last 18 months after the surgical intervention. The mechanism of this presentation, importance of early investigations, and timely intervention are highlighted in order to avoid serious neurological sequelae. The literature was extensively reviewed for atypical presentations of intraventricular colloid cyst

RESUMO

Symptomatic choroidal metastasis [CM] is a rare presenting feature of disseminated lung malignancy. Detection of the primary malignancy usually precedes ocular findings. We report a rare case of blurred vision secondary to bilateral CM as the sole initial manifestation of disseminated lung malignancy in a female patient. Pulmonary symptoms appeared 2 months later. She received radiotherapy and palliative chemotherapy and survived for 7 months after the initial presentation.

RESUMO

The aim of this study was to determine the effect of macular laser treatment on the visual acuity [VA] of Omani diabetic patients with clinically significant macular edema [CSME]. Visual outcome was also correlated with duration and control of diabetes and presence or absence of hypertension and hyperlipidemia. This is a retrospective noncomparative cohort study involving 101 eyes of 72 Omani diabetic patients. Change in VA was determined using Snellen's VA chart. The mean duration of follow-up was approximately 21 months [range, 16-24 months]. 29.7% of the patients maintained their vision, 35.6% showed improvement, whereas 34.7% showed a decrease in their vision. Positive visual outcome showed a statistically significant direct relationship with tight control of diabetes and absence of hypertension and an inverse relationship with the duration of diabetes. Presence of hyperlipedemia did not show a statistically significant relationship with positive visual outcome. However, it showed a trend to better visual outcome in the absence of hyperlipedemia. Peak incidence of macular edema was seen at the age of 52.3 years. Macular photocoagulation was found to be an effective method of treatment for CSME among Omani diabetic patients, which has resulted in a positive visual outcome in 65.3% of the patients [stable and improved vision]. Effective control of diabetes, duration of diabetes, and hypertension are the factors which influence the postlaser visual outcome
