ABSTRACT
Background: To review cases of posterior segment eye diseases (PSEDs) seen at the Eye Foundation Centre Ijebu, Nigeria in a 5 year period for planning purposes.Methods: Data was collected from patients’ case notes from January 2006 to December 2011. A systematic sampling of 468 patients from 1173 case notes of patient with (PSEDs) was done. Information retrieved was: age, sex, state of residence and diagnosis. All patients were examined by the glaucoma and the vitroretinal specialist as the case may be. They had visual acuity, refraction, slit lamp examination (including intraocular pressure (IOP) with Goldman applanation tonometer), and dilated fundoscopy with (bilateral indirect ophthalmoscopy) BIO, slit lamp using 20 D, 78 D and 90 D respectively. The glaucoma patients in addition had central visual field (CVF), Central cornea thickness (CCT), fundus photograph and in some cases optical coherence tomography (OCT) done in addition to the above.Results: The mean age was 59.98 years (SD 17.67) and the age range is 5-95 years. Males outnumbered females by 63% to 37%. The diseases were more common in age group 61 to 80. Patients’ attendances were mostly from Ijebu division of Ogun state (57%). Glaucoma is the commonest cause of attendance 262 (56%) followed by diabetic retinopathy 29 (6.2%) and age-related macular degeneration (ARMD) 28 (6.0%).Conclusions: Glaucoma, diabetic retinopathy and ARMD were noted as the commonest PSEDs in Ijebu division in Southweste
ABSTRACT
Objective: The aim of this study was to compare intraocular pressure [IOP] measured with the Tono-Pen[registered] to that measured using the Goldmann applanation tonometer [GAT] in patients with primary open angle glaucoma attending a glaucoma clinic
Subjects and Methods: A comparative clinic- based observational study was conducted involving 75 patients [39 men and 36 women] attending a glaucoma clinic in Southwest Nigeria. A pretested structured questionnaire was used to collect sociodemographic data. The Tono-Pen and the GAT were used to measure the IOP in each patient. Central corneal thickness [CCT] was measured with an ultrasonic pachymeter, and the corrected GAT value was calculated for each patient. The Tono-Pen readings were compared with the uncorrected and corrected GAT readings. Descriptive and comparative analyses were performed. Values for p < 0.05 were considered statistically significant
Results: The mean age of the participants was 60.39 +/- 16.71 years. The mean IOP using the Tono-Pen was 21.1 +/- 6.8 mm Hg versus the mean uncorrected GAT value of 17.1 +/- 6.9 mm Hg and the corrected GAT value of 18.9 +/- 7.5 mm Hg. The mean CCT was 510.5 +/- 29.6 micro m. The mean differences between the Tono-Pen reading and uncorrected and corrected GAT readings were 3.9 +/- 2.6 and 2.1 +/- 3.5 mm Hg, respectively. Gender [Tono-Pen vs. GAT; p = 0.981 vs. 0.437] and corneal thickness [p = 0.057] did not significantly affect the IOP value. Of the 75 patients, 68 [90.7%] preferred the Tono-Pen to the GAT
Conclusion: In this study, the Tono-Pen gave a higher value for IOP than the uncorrected and corrected GAT values. Gender and corneal thickness did not significantly affect the measurements. Most patients found the Tono-Pen more acceptable than the GAT
