Background: Cystoid macular edema (CMO) represents a common pathologic sequel of the retina. This study aimed to study the occurrence of cystoid macular edema in patients with retinal vein occlusion. Materials and methods: We reviewed retrospectively the medical records of 54 retinal vein occlusion patients in Makkah eye hospital in Aden, from January to December 2021. The collected data analyzed by SPSS version 22. Chi-square test was used and a p-value less than 0.05 was determined as statistically significant. Results: The total study patients with retinal vein occlusion (RVO) were 54, (males 63.0% and females 37.0%). The mean age was 58.2 ± 12.7 years. The most side involvement of branch retinal vein occlusions (BRVO) was in the right eyes with (25%) and of central retinal vein occlusions (CRVO) in (30%), (p > 0.05).The total number of eyes with RVO was 60 eyes, of which 26 eyes were with BRVO and 34 eyes with CRVO. In eyes with BRVO (35.0%) developed CMO while in eyes affected by CRVO, (31.7%), (p < 0.05). We found higher intra-ocular pressure (IOP) > 21 mmHg in CRVO with (18.4%) while in BRVO were in (8.3%), (p > 0.05).There was a positive correlation between hypertension and RVO (P < 0.05) and there was no significant relation in this study between glaucoma and occurrence of RVO (p > 0.05). The visual acuity after receiving the Avastin injections improved in all visual acuity groups. Conclusion: In this study, males were predominant. The CRVO was the commonest type of RVO. Some patients with CRVO and BRVO developed CMO. The relation between values of BRVO and CRVO related to the occurrence of CMO was statistically significant (p < 0.05).

Background: Pseudoexfoliative glaucoma is the most common type of secondary open-angle glaucoma. Objective: To describe the proportion and clinical features of pseudoexfoliative glaucoma among glaucomatous patients Materials and method: A retrospective chart review. The collected data were sex, age, family history, clinical features, clinical eyes examination, type of treatment and intraocular pressure outcome. SPSS version 17 was used. Data were presented as frequencies and means. The statistical significance of differences between data was evaluated using Fisher test. P < 0.05 was considered to indicate statistical significance. Results: The proportion of PEXG patients among glaucoma patients was (9.1%). (Females 51.2% and males 48.8%). The mean age of the patients is 67.6 ± 9.8 years. The patients of the age group 60 – 69 years old were predominant. 65.1% had bilateral PEXG. Severe visual impairment (27.9%) found in the right eyes and (34.9%) were in the left eyes. Round regular react pupils were (60.5%) in the right eyes and (74.4%) in the left eyes, followed by relative afferent pupillary defect with (27.9%) in the right eyes and (11.6%) in the left eyes. High IOP > 21 mmHg found in (60.5%) the right eyes and (53.5%) in the left eyes. The cup/disc ratio with > 0.5 in the right eyes of the PEXG patients found in (60.1%). The means of cup/disc ratio in the right and the left eyes were 0.65 ± 0.26 and 0.67 ± 0.28 respectively (p < 0.05). The medication treatment was given for (76.7%) patients and medication + surgical treatment was given for (23.3%). Conclusion: PEXG was more frequently observed in females. The proportion of PEXG patients was (9.1%). Severe visual impairment was predominant in both eyes. A population-based study suggests to further define the prevalence and characteristics of PEXG in Aden and the surrounding governorates.

The objective is to determine the demographic characteristics, and the proportion of associated factors of cataract. This was a hospital based cross-sectional study among adult patients attending Makkah hospital in Aden. We obtained all demographic and associated factors of cataract. SPSS 17 version was used. All variables were compared according to the sex and age groups. Variables were expressed as the mean ± standard deviation. Chi-square analysis was used. A P-value of less than 0.05 was considered statistically significant. The study patients were 186 cataract patients, (Females were 51.1% and males were 49.9%). The age of the patients ranged between 25 to 92 years and the mean age was 61.1 ±11.1 years. The majority patients (82.8%) were of the age group > 50 years. Most of the patients were from urban 56.5%. About (15.6%) cataract patients were smokers. Most of smokers were males 12.9%. One hundred and eleven (59.7%) of the patients gave history of exposure to sunlight, (p = 0.000). Housewives represented (39.2%), (p=0.000). About (14.7%) of the patients were diabetic. Cataract is the commonest cause of visual impairment worldwide and though it affects all age groups. It is more prevalent among people aged 50 years and more. Old age patients from urban and rural areas are the most commonly affected by cataract.
