PURPOSE: The aim of this study is to analyze the distribution of visual field (VF) mean defect (MD) in six subgroups of glaucoma patients at baseline and follow-up.
METHODS: We assessed glaucoma patients treated in a Spanish tertiary care setting with a follow-up of at least 10 months. We have included 1036 visual fields and the following glaucoma subtypes: open-Angle Glaucoma (OAG); Angle-Closure Glaucoma (ACG); Congenital Glaucoma (CG); Ocular hypertension (OHT); Pseudoexfoliative Glaucoma (PSXG); Pigmentary Glaucoma (PG). We have calculated the baseline MD and the progression MD. We have stratified the MD progression in slow (MD rate > -0.5 dB/year); moderate (MD rate between -0.5 and -1 dB/year) fast (MD rate between -1 and -2 dB/year) and catastrophic (<-2 dB/year) progression and their glaucoma subtype.
RESULTS: The glaucoma types with the worse baseline MD were CG and PG. We found significant differences after comparing the baseline MD of CG and OAG, ACG, OHT and between PG and OHT. Concerning the MD progression rate: OAG 73.54% showed slow MD progression rate; 9.85% fast; 7.3% moderate and 9.3% catastrophic. ACG 82.22% slow; 8.89% moderate; 2.22% fast and 6.67% catastrophic. CG 68.83% slow; 9.09% fast; 7.79% moderate and 14.29% catastrophic. OHT 88.6% slow; 6.14% moderate; 4.39% fast and 0.88% catastrophic. PSXG 63.24% slow, 13.24% moderate; 8.8% fast and 14.7% catastrophic. PG 89.29% slow; 3.57% moderate and 7.1% fast.
CONCLUSIONS: The CG requires special attention because of its aggressive presentation and progression.
