  • Analysis of the mutations of rhodopsin gene in autosomal dominant retinitis pigmentosa family

    Objective To detect and analyse the mutations in rhodopsin gene of members in a family affected by autosomal dominant retinitis pigmentosa (ADRP). Methods Using the polymerase chain reaction (PCR), we amplified exon 1-5 of rhodopsin gene in patients with ADRP,and analyzed it with direct sequence measuement. Results The Gly-182-Asp mutation in the rhodopsin gene was detected in most of affected members of this ADRP family, but no mutation was detected in two affected members and the control ones. Conclusion We cannot regard the Gly-182-Asp mutation in the rhodopsin gene as the pathagenic factor of the ADRP family. It is likely there is a new gene next to the rhodopsin gene.

  • Correlation of choroidal thickness and visual function in retinitis pigmentosa patients

    ObjectiveTo analyze the subfoveal choroidal thickness in retinitis pigmentosa (RP) patients and to evaluate the correlation between the subfoveal choroidal thickness (SCT) and visual function. MethodsTotally 42 RP patients (84 eyes) and 49 age and diopter-matched normal controls (98 eyes) were enrolled in this study. All the patients were taken the enhanced depth imaging technique of optical coherence tomography (EDI-OCT) examination for the measurement of the SCT. The covariate analysis was used to analyze the interaction effect between age and group. Then the SCT was amended. The RP patients were examined by 30°visual field test (T32 or LVC program) and electroretinogram (ERG) test. 32 eyes examined by T32 program, 52 eyes examined by LVC program. The waveform of ERG, mean sensitivity (MS) and mean defect (MD) were recorded. The relationship of SCT, MS and MD were analyzed by Pearson correlation analysis. ResultsThe SCT of RP patients and controls were (223.12±69.59), (288.29±52.36) μm. The covariate analysis of covariance with different age group interaction was not statistically significant (F=1.619, P=0.205), as amended SCT of RP patients and controls were (217.34±6.60), (293.20±6.00) μm, respectively. The SCT was decreased in RP patients (t=7.042, P < 0.001). Among 84 eyes, bright cone response weaken in 35 eyes, scotopic rod response weaken in 31 eyes. The difference of SCT in different ERG waveform was not significant (t=-0.976, -1.584; P=0.332, 0.117). The MS and MD of 32 eyes using T32 program were (9.05±6.42), (18.84±6.30) dB, the SCT was (209.83±71.48) μm; the MS and SCT of 52 eyes using LVC program were (7.14±5.03) dB and (228.32±66.32) μm. The SCT was related to MS (r=0.494, P=0.003) and MD (r=-0.448, P=0.009) in eyes using T32 program. There was no correlation between SCT and MD in eyes using LVC program (r=-0.232, P=0.095). ConclusionsThe SCT of RP patients is thinner than that of normal controls. The SCT of RP patients is related to MS and MD of T32 program, but not correlated to ERG waveform and MS of LVC program.

  • Characteristics Indocyanine green angiography in Vogt-Koyanagi-Harada syndrome

    Objective To investigate the cilinical value of indocyanine green angiography(ICGA) in patients with Vogt-Koyanagi-Harada syndrome(VKH). Methods Fundus fluorescein angiography(FFA) and indocyanine green angiography(ICGA) were used for comparative analyses in 26 cases(52 eyes)of VKH. Results In the acute stage of VKH,FFA revealed the multifocal leakage in the pigment epithelium and the multifocal serous retinal detachment,and the typical FFA manifestations disappeard following treatment.In the acute stage of the disease the ICGA showed:(1)numerous patchy areas of hypofluorescence and decreased flurescence in large and middle choroidal vessels(66.7%);(2)dilatation of the choroidal vessels(70.8%)and(3)in latephase of ICGA,the patchy areas of hyperfluorescence(79.2%).During the recovery stage of the disease,the abnormal undings in ICGA were resolved slower than those found in FFA. Conclusions ICGA may assist in providing valuable informations on choroidal circulation of VKH and be useful in evaluating the curative effects. (Chin J Ocul Fundus Dis,20000,16:9-11) 
