PURPOSE: To investigate anterior segment parameters in obese patients in comparison to healthy individuals. METHODS: Thirty-four obese subjects and 34 age-sex-matched healthy subjects were enrolled in this prospective cross-sectional study. Ophthalmological examinations including intraocular pressure (IOP), central corneal thickness (CCT), anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle (ACA), and axial length (AL) measurements were performed on each subject. Height and weight of all subjects were recorded and body mass index (BMI) was calculated. RESULTS: IOP was significantly higher in the obese group (p = 0.003). The mean ACD in obese subjects was significantly lower than that in control subjects (p = 0.036). AL, ACV, ACA and CCT were not significantly different between the groups. There was a positive correlation between BMI and IOP (r = 0.404, p < 0.001). ACD and ACA were negatively correlated with BMI. CONCLUSIONS: IOP was significantly higher and ACD was significantly lower in obese subjects. AL, ACV, ACA and CCT were not significantly different between the groups. The impact of obesity on anterior chamber parameters should be further investigated.

Orbscan-II anterior system was used for early diagnosis of keratoconus. 48 Eyes of 24 patients with suspicious keratoconus were examined by Orbscan-II anterior system from Dec. 1999 to Dec. 2000 and followed up. The values of Diff and anterior chamber depth (ACD) were recorded. Results indicated that values of Diff and ACD were increased in 4 eyes of 2 patients with keratoconus trend during follow-up. Taking advantage of Orbscan-II anterior system to observe the values of Diff and ACD can early diagnose the sub-clinical keratoconus. The values of Diff and ACD can sensitively report the progression of keratoconus.

PURPOSE: To evaluate the influence of biometric variables on refractive outcomes after cataract surgery in angle-closure glaucoma (ACG) patients. METHODS: In this case-control study, 42 ACG patients, 40 open-angle glaucoma (OAG) patients, and 35 controls without glaucoma who had undergone conventional cataract surgery were enrolled consecutively. Electronic medical records, including preoperative biometric variables (keratometric diopter, axial length, anterior chamber depth, and lens thickness), the refractive change (RC), and the absolute value of refractive change (ARC) were reviewed. RESULTS: In the control and OAG patients, the anterior chamber depth was negatively correlated with the ARC (r = -0.344, p = 0.043 and r = -0.431, p = 0.006, respectively), whereas there was no correlation in the ACG patients. Lens thickness was positively correlated with the RC, but not with the ARC, in the control and OAG groups (r = 0.391, p = 0.020 and r = 0.501, p = 0.001, respectively). In contrast, lens thickness in the ACG group was not correlated with the RC but was positively correlated with the ARC (r = 0.331, p = 0.032). CONCLUSIONS: In contrast with the anterior chamber depth, preoperatively measured lens thickness may be a useful predictor of the direction of the RC after cataract surgery in control and OAG patients. However, in ACG patients, a thicker lens was correlated with a larger RC, regardless of the direction of the shift (hyperopic or myopic).

PURPOSE: To report multimodality diagnostic imaging in a case of unilateral acute idiopathic maculopathy. CASE SUMMARY: A 32-year-old woman with reduced vision in the right eye had experienced fatigue and flu-like symptoms, including sore throat and fever a few days before. Her best corrected visual acuity (BCVA) was 1.0 in the right eye. There were no cells in the anterior chamber and vitreous. Fundus photographs of the right eye on presentation showed gray-white thickening of the fovea and retinal hemorrhage next to the fovea. Fluorescein angiography demonstrated ring-shaped mottled hyperfluorescence in the early phase and dye pooling in the late phase. Spectral-domain optical coherence tomography (OCT) showed abnormal hyper-reflective thickening at the level of the outer retina and retinal pigment epithelium (RPE) and detachment of the neurosensory retina in the foveal lesion. The inner segment/outer segment junction and photoreceptor elevation/disruption was noted. Nineteen months after onset, the BCVA of the right eye was 1.0 and fundus photographs showed increased retinal pigment hyperplasia, and residual RPE changes resembling a bull's eye maculopathy. The OCT of the right macula showed that the inner segment/outer segment junction elevation/disruption almost completely regressed. The patient was diagnosed with unilateral acute idiopathic maculopathy. CONCLUSIONS: We report a typical case with flu-like symptoms of unilateral acute idiopathic maculopathy. It is a very rare macular disease and a case such as ours with long-term follow-up using multimodality diagnostic imaging has not been previously reported.
