The impact of glaucomatous visual field defects on reading speed and eye movement analysis / Shauqiah Muhamad Jufri

Visual field plays an important role on information retrieval for mobility and navigation in daily activities. Reading is one of the activities to retrieve information for knowledge acquisition in native and non-native language, which affect differently. The first part of our study was to develop a...

Reading is one of the activities to retrieve information for knowledge acquisition in native and non-native language, which affect differently. The first part of our study was to develop a standardised reading passage as a tool to evaluate reading in the Malay language. The development of the reading passages encompassed three stages: exploratory, confirmatory and prototyping. In the exploratory stage, 300 sentences extracted from standard school textbooks endorsed by the Malaysian Ministry of Education based on two deciding factors. A total of 56 passages constructed with equal readability, based on a "5 continuous sentence structure of 50 words" combination. In the confirmatory stage, the 56 passages verified by twenty-five normal sighted native Malay speakers. The reading time measured using a stopwatch, while the errors marked in recording sheet. Reading speed quantified in words per minute (wpm). Three passages eliminated from the confirmatory testing based on the outliers present in the boxplot graph. Eleven passages further eliminated based on the 10 % highest error and best 5 % at the two extreme ends of the reading speed range. In the prototyping stage, 42 reliable, qualified reading passages randomly compiled into 3 sets with 13 passages each of SAH reading passage compendium (SAHRPC). This newly developed SAHRPC used in the main study investigating the effect of glaucomatous VFD on reading speed and eye movement analysis. Sixteen participants recruited using convenient sampling. Eight patients who diagnosed with glaucoma from a tertiary ophthalmology clinic grouped under the experimental category. Eight normal-sighted participants placed under the control group. Inclusion criteria was best-corrected visual acuity of 0.8 LogMAR or better. Visual field tested using the Humphrey Matrix 24-2 threshold protocol for all participants. Participants asked to read randomly selected reading passages monocularly. The duration to complete the passages measured using a stopwatch and errors made marked onto the recording sheets. Reading speed calculated in wpm. Eye movements measured indirectly during reading of the passages with Three-D video-oculograph (3D VOG).
