Differentiating full thickness macular holes from impending macular holes and macular pseudoholes

AIMS—The reliability of scanning laser ophthalmoscope (SLO) microperimetry in differentiating full thickness macular holes from macular pseudoholes and impending macular holes was evaluated.
METHODS—106 eyes with the clinical diagnosis of full thickness macular holes, macular pseudoholes, and impending (stage 1) macular holes were examined for the presence of deep or relative scotoma using SLO microperimetry. The relation between these scotomas and the clinical diagnosis was studied.
RESULTS—Deep and relative scotomas were detected in all 57 eyes with clinically defined full thickness macular holes. In contrast, among 49 eyes diagnosed with macular pseudoholes or impending macular holes, no deep and only one relative scotoma was observed. The sensitivity of the presence of a deep scotoma as an indicator of the clinical diagnosis of a full thickness macular hole was 100% (57 of 57), and the specificity was 100% (49 of 49). The sensitivity of the presence of a relative scotoma was 100% (57 of 57) and the specificity was 98.0% (48 of 49).
CONCLUSION—With SLO microperimetry, full thickness macular holes can be precisely and objectively distinguished from other conditions that mimic macular holes.

     

Best's macular dystrophy with a macular hole

The occurrence of a macular hole with Best's dystrophy is an extremely rare finding with only one reported case in the literature. We wish to report two cases with typical Best's dystrophy in one eye and a macular hole in the contralateral eye. In one case the Pattern Reversal VER (PVER) was also recorded and graphed as an amplitude-check size function curve. The PVER changes in this case were grossly subnormal in both the eyes, suggesting a significant degree of bilateral macular impairment. This implies that a significant amount of functional impairment occurs at the vitelliform stage itself, though how this stage progresses to a macular hole is unclear.

Multimodal evaluation of macular function in age-related macular degeneration

Objective

To evaluate macular function using multimodality in eyes with age-related macular degeneration (AMD) at various stages.

Methods

Macular function in 20 control eyes (20 subjects), 17 eyes (17 patients) with large drusen, 18 eyes (18 patients) with drusenoid pigment epithelial detachment (PED), and 19 eyes (19 patients) with neovascular AMD was examined using a Landolt chart for visual acuity; retinal sensitivity was measured by microperimetry; and focal macular electroretinography (fmERG) was performed. In all of these eyes, retinal morphology was examined using optical coherence tomography.

Results

Eyes with neovascular AMD showed morphologic changes in the neurosensory retina as well as marked deterioration of macular function in all parameters measured with a Landolt chart, fmERG, and microperimetry. Eyes with large drusen showed only minimal morphologic changes in the neurosensory retina. In this large drusen group, although retinal sensitivity at the central point was significantly decreased (P = 0.0063), the other parameters of macular function were well preserved. In eyes with drusenoid PED, the structure of the neurosensory retina was well preserved, while the foveal thickness was significantly increased (P = 0.013). The macular function of these eyes was significantly deteriorated, with the VA, amplitude of the a-wave and b-wave, and retinal sensitivity being markedly decreased. In addition, the area of PED correlated with the latency of the a-wave and b-wave and with the retinal sensitivity within the central 4° or 8° region.

Conclusion

Multimodal evaluation demonstrated a significant decrease in macular function in drusenoid PED and in neovascular AMD.     

Comparison of macular pigment in three types of macular telangiectasia

Purpose

To compare macular pigment in three types of macular telangiectasia (MacTel).

Methods

Twenty-six eyes of 16 patients (mean age, 62 years) with MacTel were examined. The macular pigment optical density (MPOD) was obtained by autofluorescence spectrometry using two wavelengths (488 nm, 514 nm). The density of the central macular pigment within 0.5 degree around the foveal center (MPODc) was measured from a MPOD map.

Results

Eight eyes of seven patients were classified as type 1, 16 eyes of eight patients as type 2, and two eyes of one patient as type 3. The macular pigment signal was seen in the area of fluorescein leakage in type 1 and the occlusive area in type 3; the macular pigment signal decreased in the area of fluorescein leakage in type 2. The mean MPODc (± standard deviation) was 0.40?±?0.16 density unit (DU) (range, 0.17-0.57) in type 1; ?0.08?±?0.15 DU (range, ?0.29–0.25) in type 2; and 0.32?±?0.08 DU (range, 0.26–0.37) in type 3. Significant differences were seen between types 1 and 2 (P?<?0.001) and types 2 and 3 (P?=?0.007). There was no significant difference between types 1 and 3 (P?=?0.765). In 30 age-matched normal eyes, the MPODc was 0.58?±?0.11 DU (range, 0.38–0.79). There were significant differences between normal eyes and each MacTel subtype (type 1, P?=?0.007; type 2, P?<?0.001; type 3, P?=?0.043).

Conclusions

The macular pigment values and distributions, including leakage or occlusion, differed in each MacTel type compared with fluorescein angiography findings. The capillary occlusion in type 3 is not associated with reduced MPOD.     

Spontaneous macular hole closure in bilateral macular holes

The natural course of full thickness macular hole is progression in size and stage. There have been reports of spontaneous closure of unilateral idiopathic full thickness macular holes, but we report the first case of spontaneous closure of a full thickness macular hole in one eye in a patient with bilateral idiopathic full thickness macular holes. After macular hole surgery in the left eye of the patient, spontaneous closure of the macular hole in the right eye was observed during the follow-up period.
