Distribution of ophthalmologists and optometrists in Islamic Republic of Iran and their associated factors

We aimed to determine the distribution of ophthalmic care providers and its correlation with health and socioeconomic status and health system indicators. Data were gathered from the Iran Medical Council and the Iranian Societies of Ophthalmology and Optometry. Concurrent indicators were collected from the Statistical Center of Iran and national studies. A population-adjusted number of combined ophthalmologists and optometrists was used as the main dependent variable. Optometrist/ophthalmologist ratio was 0.9. We had 1 ophthalmologist and 1 optometrist for every 40 000 and 45 000 individuals, respectively. We observed a direct correlation between the number of ophthalmologists, optometrists and life expectancy at the provincial level. Gross provincial income and expenditure and provincial literacy were correlated as well. Provincial unemployment had a negative correlation. Provincial hospital statistics and population density were also significantly correlated. The Islamic Republic of Iran has met the World Health Organization's desired per capita number of ophthalmologists and optometrists, but there is wide variation in their density

[Nd:YAG membranotomy in diabetic premacular hemorrhage]

To evaluate the success rate of Nd:YAG laser membranotomy in patients with diabetic premacular hemorrhage. This interventional case series included 24 eyes of 22 patients referred to retina clinic of Farabi Eye Hospital, Tehran, Iran during 2000-2007 with chief complaint of sudden loss of vision and clinical diagnosis of premacular hemorrhage due to proliferative diabetic retinopathy. All patients underwent complete ocular examination and color fundus photography. Nd:YAG laser membranotomy was performed in patients with >3 DD hemorrhage. Main outcome measures were success rate of membranotomy, improvement of visual acuity and the complications. Twenty-four eyes of 22 patients [68.2% female and 31.8% male] with diabetic premacular hemorrhage were enrolled. Mean age of patients was 56 +/- 6.5 years. Nd:YAG laser membranotomy was successful in 71% of patients resulting in release of trapped blood into the vitreous cavity which absorbed during 14.3 +/- 5.03 [range 8 to 27] days. Range of preoperative visual acuity was from hand motion to count finger at 4 m which improved to a range of 20/100 to 20/25 postoperatively. Patients complained of some visual disorders such as blurred vision and floater over 23-86 days [mean 43 days], postoperatively. Macular photocoagulation was performed in 11 eyes with macular edema before panretinal photocoagulation. Mean follow-up period was 34.7 +/- 18.3 [range 10-71] months. Nd:YAG laser membranotomy in diabetic premacular hemorrhage is a simple and inexpensive outpatient procedure which results in rapid visual recovery and is relatively safe. Further controlled clinical trials are recommended
